Taishin International Bank (TSIB)

Senior-programmer / RDSS
  • — [Batch Refactoring & UX Optimization] Addressed a critical limitation in a 2–3 hr monthly risk-management batch blocked by the .NET page lifecycle. Decoupled the process into async DB writes + AJAX polling, delivering a real-time progress bar and interrupt alert system.
  • — [System Integration & Data Migration] Supported the Taishin–ShinKong merger: coordinated and verified schemas for 10M+ rows of incoming data from ShinKong Financial, integrated the data sources, and modified existing batch execution applications accordingly.
  • — [Technical Leadership & Mentorship] Mentored onboarding engineers through dev-environment setup and system walkthroughs; coordinated task distribution to align with project timelines.
  • — [Automated Data Validation] Built a Python (Pandas) pre-import validation utility that identifies layout anomalies in source files, eliminating migration interruptions caused by malformed data.
  • — [Efficiency Gains] Guided team members on integrating AI assistant tools into daily workflows, increasing team-wide code writing and debugging throughput.

case study ↗ Personal Project WhoWins Triggered by personal inconvenience with scoring during intense badminton matches, engineered a production-ready monorepo tracking ecosystem bridging Web, Android, iOS, Wear OS, and watchOS clients.
Formulated a strict Centralized Single-Source-of-Truth engine to handle intricate badminton server rotations, positions, and an exact pre-rally undo snapshot stack, keeping all frontends completely stateless regarding business logic.
Built multi-tier containerized (Docker) CI/CD deployment pipelines on GCP e2-micro and Cloudflare Pages, implementing custom per-IP rate-limiting middleware and a direct-to-token FCM multicast mechanism to bypass cross-project service account restrictions.
Devised a structured AI co-work framework using a document-first approach and rigid path isolation to optimize Claude AI's performance across 4 distinct programming languages, ensuring seamless cross-platform feature synchronization.
